The Western Pennsylvania Conservancy has completed a comprehensive three-year, $7 million restoration of Frank Lloyd Wright’s architectural masterpiece, Fallingwater. The project focused on critical structural vulnerabilities, including moisture degradation of interior finishes, leaking windows and doors, and the installation of a new waterproof roof. Experts addressed specific design flaws inherent to Wright’s original 1935 construction, such as the lack of through-wall flashing and the use of river pebbles in concrete aggregate, which had exacerbated the building's battle against the elements.
Maintaining a structure built directly over a waterfall presents unique engineering challenges that require constant, high-stakes preservation efforts. As a UNESCO World Heritage site, Fallingwater represents a pinnacle of organic architecture, and this overhaul ensures the iconic residence remains structurally sound for future generations. The project highlights the ongoing tension between Wright's ambitious aesthetic visions and the practical realities of long-term conservation in a high-moisture environment.
